Issue description: Start from the following setting

1. Click on the swatches' Hex color tab and right click on the edit.
2. The popup closes immediately and the RGB node changes to Hex as well.

You can achieve the same effect by clicking on HSV and changing one of the sliders. Then the RGB node's tab also changes to HSV. The same holds for the RGB tab, too but you have to change the RGB node's tab first in order to see a switch there.

the reason for this is that the colorWheel state is shared among all color pickers in Ext.hx static var wheelSelectedHande: Handle = null;
